Bug 365214

Description Andrei Diaconu 2011-11-30 10:53:17 EST

To reproduce the bug, do the following using the snippet given below:

* click anywhere on the shell without trim (a popup menu appears)
* click on the menu item

You will notice that no selection event has been generated.


import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.*;

public class NoSelectionEvent {

	public static void main(String[] args) {
		final Display display = new Display();
		final Shell shell = new Shell(display);
		shell.open();

		final Shell secondShell = new Shell(shell, SWT.NO_TRIM);
		final Listener listener = new Listener() {
			@Override
			public void handleEvent(Event event) {
				switch (event.type) {
					case SWT.MouseUp:
						final Menu menu = new Menu(secondShell, SWT.POP_UP);
						final MenuItem menuItem = new MenuItem(menu, SWT.NONE);
						menuItem.addListener(SWT.Selection, new Listener() {
							@Override
							public void handleEvent(Event event) {
								System.out.println("menu item selected");
							}
						});
						menu.setVisible(true);
						break;
					case SWT.MouseExit:
						secondShell.dispose();
						break;
				}
			}
		};
		secondShell.addListener(SWT.MouseUp, listener);
		secondShell.addListener(SWT.MouseExit, listener);
		secondShell.open();

		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}
		display.dispose();
	}
}



I need this dispose-on-exit behavior for tools that appear on hover, sort of rich tooltips.
